In situ high-resolution valence photoelectron spectra of a peanut-shaped C60 polymer.

To elucidate the origins of the metallic properties of the peanut-shaped C60 polymer, we examined the valence photoelectron spectra of the polymer using in situ high-resolution photoelectron spectroscopy and found that the density-of-states (DOS) of the polymer clearly comes across the Fermi edge in a manner similar to that of Au film used as a reference, indicating that the peanut-shaped C60 polymer exhibits metallic properties.
